AUTOMOBILE RADIATOR CAP.

Application filed November 3, 1924. Serial No. 747,432.

To all whom t may concern:

Re it known that I, ALoYsrUs C. LIPPERT, a citizen of the United States,residing in Kenosha, in the county of Kenosha and State of IViScOnSin,have invented a new and useful Improvement in Automobile Radiator Caps,of which the following is a specification.

rlhe present invention relates to closures for automobile radiators andthe like, and has for a principal object the provision of a radiator caphaving the general advantages described and claimed in copendingapplication Serial No. 747,434, of Aloysius C'. Lippert and Anthony H.I-Iackl, and in addition thereto having provisions for attachment to theradiator neck which facilitate adaptation of the cap to radiator necksof dierent size.

A. further object ofthe invention is the provision of a radiator cap ofthe general type of the copending application above referred to,provided with sealing means which may, perhaps, be preferred to thatshown in said co-pending application and which sealing means, as well asthe remainder of the construction, may be inexpensively provided so thatvthe cap may be placed upon the market at relatively low cost.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, whiclntakenin connection with the accompanying drawings, discloses a preferredembodiment thereof Referring to the drawings,

Figure 1 is a front elevation of a radiator cap in which the inventionis embodied, the same being shown in position upon the filler neck of aradiator and being partially broken away and sectionalized forconvenience in illustration; and

Figs. 2 and 3 are horizontal sectional views, taken respectively uponthe section lines 2-2 and 3-3 of Fig. 1.

In said drawings, I have shown, for illustrative purposes only, apreferred form of my invention, in which the reference character 11indicates an outer body, having laterally extending arms 12 and beingprovided with a hinged cover 13, adapted to carry a motometer 14, orlike device, a latch 15 being provided to hold said cover tightly to thebody and in contact with a gasket 16,

of rubber or like material, suitably posit-ioned upon the interior ofsaid body. An inserted locking member 17, of brass or like workablematerial, is disposed in a central opening 18 in said body and in thepresent instance is adapted to be locked to said body by means ofintegral projections 19, extending into a circular groove 21 formed onthe interior of the cap body, it being apparent that with thisconstruction, said body may be rotated relatively to the insert, butseparation of the parts is prevented and the rotation ofl the body willnot tend to remove said insert from the radiator neck. Said insert 17,at the lower end thereof, is bent back upon itself, as indicated at 22and .the inner, upwardly extending portion 23 thus provided is threaded,as indicated at 24, and adaptedto screw upon the radiator neck 25. Theupper extremity of the portion 23 of said insert is bent slightlyoutwardly, asv shown at 26, and then inwardly andi downwardly to providean edge portion 27 adapted to tightly contact with the top' of saidradiator neck when the insert is screwed down to the position shown inFig. 1. It will be manifest that the diameter of the threaded portion 23of thel insert may be varied in accordance with the manner in which saidportion is bent from the body of said insert, thereby to accommodateradiator necks `of different size, the diameter of the-body of theinsert-being the same for all sizes and the threaded portions beingdisposed at any desired distance from said body, in manner which will bereadily understood. r[hns the inserts may be provided for vattachment tothe varying sizes of radiator necks by merely disposing thel threadedportions 23 thereof at dierent distances from the body, the remainingoperations and the construction and sizes of the other parts being thesame for all radiators.

For the purpose ,of screwing the cap onto the radiator, I employ aratchet member 28, disposed in a recess 29 in the insert and having aprojecting edge part 31 adapted to engage in recesses 32 formed in theouter cap body and engageable when said outer body is ro-tated in onedirection only. One of the recesses 32 extends to the bottom of theouter body, as shown in Fig. 1, to facilitate the assembly of the bodyand insert with the ratchet member 28 in position, and it will beunderstood that the number of ratchets and of said recesses might beincreased, if desired. I prefer, however, to provide said recesses atopposite sides of the cap., inwardly from the projecting arms 12, asshown in the drawings, since there is more stock in this area and thegrooves` are less likely to weaken the cap body.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention, or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

I claim:

l. A radiator cap for automobiles or the like, comprising an outer body,and an inserted locking member secured thereto and permitting relativerotation of the outer body, the lower end of said inserted member beingbent inwardly within the body portion thereof and threaded ierattachment to the radiator neck.

2. A radiator cap for automobiles or the like, comprising an outer bod",and an inserted locking member secured thereto and aermitting relativerotation of the outer body, the lower end of said inserted member beingbent inwardly within the body portion thereof and threaded forattachment to the radiator neck, and having a part beyond the threadsadapted for sealing engagement with the top of said neck.

3. A radiator cap for automobiles or the like, comprising an outer body,a closure pivoted to said body, and an inserted locking member securedthereto and permitting relative rota-tion of the outer body, the. lowerend of said inserted member being bent inwardly within the body portionthereof and threaded for attachment to the radiator neck.

4. A radiator cap for automobiles or the like, comprising an outer body,a closure pivoted to said body, and an inserted locking member securedthereto and permitting relative rotation of the outer body, the

lower end of said inserted member being bent inwardly within the bodyportion thereof and threaded for attachment to the radiator neck, andhaving a part beyond the threads adapted for sealing engagement with thetop of said neck.

5. A radiator cap for automobiles or the like, comprising an outer body,and an inserted locking member formed of bendable material and having avertical wall and a portion bent upwardly within said wall and providedwith means for attachment to the radiator neck.

6. A radiator cap for automobiles or the like, comprising an outer bodyhaving. an opening therein, and a locking member disposed within saidopening and having throughout a part of its height a double wall, onepart of which is provided with means for attachment to the radiatorneck.

7,'A radiator cap for automobiles or the like, comprising an outer bodyhaving an opening therein, and a locking member disposed mithin saidopening and having an attaching portion arrangeable at varying distancesfrom the body part thereof, said attaching portion having an extensionengageable with the top of the radiator neck to prevent leakage.

8.Y A radiator cap for automobiles or the like, comprising an outer bodyhaving an opening therein, and an inserted locking member having adouble wall, one part of which is provided with means for attachment toradiator necks of different diameter without change of form of the bodyportion of said member.

9. A radiator cap for automobiles or the like, comprising an outer bodyhaving an opening therein, and a locking member disposed within saidopening and having an attaching portion arrangeable at varying distancesfrom the body part thereof, said locking member having an end flangeengageable with the top of the radiator neck to prevent leakage and saidfiange being rolled to provide clearance about the outer edge of theradiator neck and to stiifen the flange.
